Hitchhiker ID please

[Candace Summers]

So all of a sudden I see a hundred or more of these guys in my holding tank. Can anyone ID? The videos show it the best.

Do the videos work for you? Definitely doesn’t look like a flat worm. It doesn’t have the 3 points and it has a crunch when squished

Elysia SP. It's a type of slug

Its an hawaiian sea slug known as Vayssierea felis which are found on and under rocks most commonly.

Omg you got the jackpot!! From http://seaslugsofhawaii.com/species/Vayssierea-felis-a.html
It feeds on spirorbid and serpulid polychaetes by boring through their tubes (Kay, 1979)
I need these in my tank!!

No, the videos didn't work but R2R came through with an ID anyway.

I'd like some of those if they eat spirorbids! GL!

This is definitely the closest match I have seen so far! I think this may be it and now that I look, I do seem to have way less of the spirorbid worms in that tank now (which I hated). Maybe some in the main display would be alright. Any idea how I make videos taken on an iPhone work here?

iPhone here too. I can only see videos that are uploaded to YouTube and the link posted here.

I just googled it and it said that videos from iPhone worked using chrome rather than Safari. Downloaded it, no dice. Super annoying.

Ok figured out YouTube! Lol
Excuse my kid humming in the earlier video. Hopefully this helps confirm ID, but yes so far seems like vayisseriea falis.

I’m no expert but it sure does look like what @vetteguy53081 said.

I used to have these same critters in my display tank late at night. They would scatter during the day .
